Mohd- The' Schedulexeferred to in thele Lettere Patent and 'maliiprt 0f ma me To all whom it may conce/rn.-

Be itknown that I, WILLIAM ANnnRsoN Kenn, of Easton, in the county of Northampton andy State of Pennsylvania, have invented a new and improved Printing-Press; andl do hereby declare that .the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make anduse the same, reference being had to the accompanying drawing forming part of this specication.

Figure 1 represents a front elevation of my improved printing-press.

' Figure 2 is a plan or top "iew, partly insection, of the same. i

Figure 3 is a vertical longitudinal section of the same, taken on theplane of the'line a: az, fig. 2.

Figure 4 is an inverted plan view of the same`.=

Figure 5` is an end elevation of the same.

Similar letters ofreference indicate corresponding parts.

This invention relates to improvements in rotary pressesfor printing both sides of one sheet by one process. v

The invention consists in the general arrangement of devices for operating lthev type-frames.

'.lheinvention also consists in the arrangementof carrying-bands placed around th'e cylinder and other rollers, for taking hold'of and carrying the paper to the required places.

T he invention finally consists in the combination of drums or platens and typen-ames and a suitable transferring mechanism. i

A, in the drawing, represents `theframe of. my improved printing-machine. f

In it are the bearings of two horizontal drums or cylinders, B G, which are hung in the frame close together, as shown in iig. 3.

Upon the axles ofthe drums B 'O aremounted gear-wheels a b, respectively, they being of `equal diameter, an meshing intoP each other, so that the drums can only with equal speed. 4

By means of intermediate gearing, c c,`o'f suitable kind, motion is transmitted to one ot' the drums B C from the driving-shaft D.

In the ends of the frames are grooved tracks for` the type-frames E' and F, respectively. These typeframes are perfectly flat, and are. set v,up vertically in the ends of A.

' Each type-flame carries a vertical rack, d, at its outer face, the said rack meshing into af toothed wheel, e, which receives oscillating motion by means of a connecting-rod, f, from astvingng lever, 'g.

`The ends of the frame A are, at- 'their free` ends, connected with -each other by means of a bar, h.

This bar is, by a rod, t', connected with a cog revolve in opposite'direetions, but

'wheel-of the train c, and is, as said wheel revolves, moved up and down in slotted vertical guides of the frame A. The bar h, by swinging -the levers 'g, imparts the required reciprocating motion to the frames E and F.

The paper to be printed is rst placed upon the drum B, onto 'a set of iiexible bands@ j, that vpass around the same. l r l These bandsj are laid around the drum '13, and around asmaller roller, l, which is held close to 'the inner sideof` the drum O.

The latter drum carries similar bands, fm., which pass around rollers, no, the latter being underthe drum B, so that, from Z too, thel bands j fm.- are close together.

A third set'of bauds,`p, ls arranged under the drum Y C ,passing over rollers 'r 4', of which one receives rotary motion by means of a pinion, s, from the train c. ",lhe paper to be printed is, as above stated, rst placed uponl the drum B, and is on thesame held by the fingers t t, .and carried against the type-frame E, on which its outer face is printed: l'

Then the paper is, vbetween the bandsj and m, car

ried ,toward lthe drum il, and is on the same fastened -by other fingers, ,tj t', which hold'it'avhileits unprinted side is 'brought against the type-fra ne F, and printed by the same. v

Frein the drum' C the paper is taken to the band 1l, by which itis carried to the dischargeiingers u on a roekshaft, G. i

Therock-shaft is, by a crank, r, and a link, w, counected with a lever, x, which is pivoted to the frame A, and which, `when turned by a pin, y, of the druln B, causes the shaft G- to turn, se as to swing the iin-. 'gers u down.

Whenever the paper, after having .been printed ou ooth sides, falls upon the fingers u, the latter are swung down to discharge the same. Y

A spring, z, throws'the shaft G and lingers u up again intoA the original position.

The iingers t t are, as -usually, fastened to shafts,

H, pivoted in the drums B G, and operated by fixed stops, af, of the frame A.

Eachtype-i'ame has the'type b' in its upper pai-t, while its lower part,fc, isvmadc in form of a smooth inking-plate.

This plate c', passing alongthe surface AVo1 an ink- Y ing-roller, d', becomes inked thereby, transferring the ink, during the upward motion of the type-frame, to an upper roller, i which is hung in the frame A.l

During the n -xt downward motion of the typeframe the inkis transferred from -the roller I to the face of the type. vThe `roller dreceives the ink, by suitable intermediate rollers, from the ink-vat J,

Having thus' described my invention,

I claim as new and desire to secure by Letters Patenf- A 1. The racks d, wheels e, rods f, levers g, and bars h, all combined with the reciprocating.type-frames, to operate the same, substantially as herein shown and deseribed.

2. The band'sxj m, arranged ou and in combination with the drums B 0, substantially as herein shown Iand described, to lconvey the paper in the manner described. v

3. The drums l?,v and U, combined and. arranged with the plates E and E, :mei provided with any suitable transferring mechanism, all operating as described,

whereby the sheetsof paper may be printed on both sides during their passage throughthe press, as specified.
